Freescale SDN Mechanism Driver for Neutron ML2 plugin
|
|
=====================================================
|
|
|
|
Introduction
|
|
============
|
|
|
|
Freescale SDN (FSL-SDN) Mechanism Driver is an add-on support for ML2 plugin
|
|
for Neutron.
|
|
|
|
It supports the Cloud Resource Discovery (CRD) service by updating
|
|
Network, Subnet and Port Create/Update/Delete data into the CRD database.
|
|
|
|
CRD service manages network nodes, virtual network appliances and openflow
|
|
controller based network applications.

How does Freescale SDN Mechanism Driver work?
|
|
===========================================
|
|
|
|
- Freescale Mechanism driver handles the following postcommit operations.
|
|
- Network create/update/delete
|
|
- Subnet create/update/delete
|
|
- Port create/delete
|
|

{

|
neutron -> ML2_plugin
|
|
ML2_plugin -> FSL-SDN-MD
|
|
FSL-SDN-MD -> crd_service
|
|
FSL-SDN-MD <-- crd_service
|
|
ML2_plugin <-- FSL-SDN-MD
|
|
neutron <-- ML2_plugin
|
|
}
|
|
|
|
- Supported network types by FSL OF Controller include vlan and vxlan.
|
|
|
|
- Freescale SDN mechanism driver handles VM port binding within in the
|
|
mechanism driver (like ODL MD).
|
|
|
|
- 'bind_port' function verifies the supported network types (vlan,vxlan)
|
|
and calls context.set_binding with binding details.
|
|
|
|
- Flow management in OVS is handled by Freescale Openflow Controller.

Configuring ML2 Plugin
|
|
----------------------
|
|
|
|
In [ml2] section of /etc/neutron/plugins/ml2/ml2_conf.ini,
|
|
modify 'mechanism_drivers' attributes as:
|
|
|
|
::
|
|
|
|
mechanism_drivers = fslsdn
|
|
|
|
Configuring FSLSDN Mechanism Driver
|
|
-----------------------------------
|
|
|
|
Update /etc/neutron/plugins/ml2/ml2_conf_fslsdn.ini, as below.
|
|
|
|
::
|
|
|
|
[ml2_fslsdn]
|
|
crd_auth_strategy = keystone
|
|
crd_url = http://127.0.0.1:9797
|
|
crd_auth_url = http://127.0.0.1:5000/v2.0/
|
|
crd_tenant_name = service
|
|
crd_password = <-service-password->
|
|
crd_user_name = <-service-username->
|
|
|
|
CRD service must be running in the controller.
